Mixing 12v And 24v Solar Panels

Mixing 12v and 24v solar panels.

If your existing electrical system is 12v like in an rv which already wired and equipped with 12v appliances then you should stick with a 12v solar system. 12v vs 24v 12 volt vs. You can get much bigger inverters on 24v or 48v than 12v. You may have noticed that solar panels come in both 12v and 24v.

An important point to be noted here is that a 24v rating battery is not available in the market but you can create one by joining two 12v batteries in a series connection. You have two different higher voltage solar panels i e one 100w 24v and one 200w 24v that you want to connect to the already working 12 v solar power system comprising the two 12v 50 w solar panels connected in parallel from the previous scenario see the picture above. There are a number advantages in opting for a higher dc supply voltage. This is usually used with 12v set ups.

Now lets look at connecting solar panels in parallel. Solar modules are connected in series to obtain higher output voltage. Solar panels are connected in parallel to obtain higher output current. The maximum system voltage however must not be exceeded.

0 5v line drop at 12v 4 6 supply drop whereas 0 25 v line drop at 24v 1 04 drop. For any given load half the dc current and losses are down by. For modules connected in series total power is calculated as follows. So when connecting solar panels in series always try to keep the electrical properties of the solar panels identical to get the full benefit of the solar array.
